Abstract

Avion convertible. Il comporte des propulseurs fixes comprenant deux rotors engrénant dont les axes de rotation sont sensiblement concourants et transversaux l'un à l'autre. Le pas des pales de chacun des rotors peut varier indépendamment du pas des pales de l'autre rotor. Lesdits rotors sont disposés de manière que la résultante aérodynamique de leur action puisse varier dans un plan vertical parallèle aux deux axes et à l'axe longitudinal de l'avion. Application : avion pouvant prendre plusieurs configurations de vol, notamment une configuration correspondant au déplacement horizontal et une configuration correspondant à un déplacement verticaL
